Description

Busbar punching, shearing and bending integrated machine

Technical Field

The utility model belongs to the technical field of busbar processing equipment, and particularly relates to a busbar punching, shearing and bending integrated machine.

Background

In the field of electrical industry, a busbar (mainly comprising a copper bar and an aluminum bar) is used as a core component for current transmission and distribution, and the processing quality and efficiency of the busbar have profound effects on the overall performance and the safety and reliability of electrical equipment. With the continuous increase of power demand and the continuous complexity of electrical equipment, higher requirements are put on busbar processing technology. However, the traditional busbar processing mode generally adopts a plurality of independent devices to respectively complete the procedures of feeding, shearing, punching, bending and the like, and the mode not only occupies large area and has low production efficiency, but also is difficult to effectively ensure the processing quality. Particularly in the punching process, the existing equipment generally adopts a mode of clamping a punching surface, so that a clamp is left on the side face of the copper bar to form an indentation, and further the electrical performance, the safety and the sharp-angle discharge of the busbar are affected. Therefore, developing a highly integrated busbar punching, shearing and bending integrated machine becomes a technical problem to be solved in the current electric industry.

Busbar processing current situation and problems:

At present, busbar processing mainly depends on multi-station processing equipment, and the equipment consists of a plurality of independent modules, including a feeding device, a punching device, a shearing device, a bending device and the like. Each module requires independent operation and control, which not only increases the complexity and footprint of the device, but also reduces production efficiency. Meanwhile, due to the lack of tight coordination among the modules, the processing precision and consistency are often reduced, and the overall quality of the busbar is affected.

In the punching process, the existing busbar processing equipment generally adopts a mode of clamping a punching surface, and the busbar is fixed on a workbench through a clamp to punch. However, the clamping mode has the obvious defects that the impression generated by clamping the side surface of the copper bar not only affects the attractiveness of the busbar, but also causes sharp angle discharge phenomenon easily caused by sharp angles formed by the impression, and seriously reduces the insulation performance and the safety of the busbar. Under the application scene of high voltage and high current, the sharp angle discharge phenomenon can cause equipment failure and even safety accidents, and the stable operation of the electrical equipment is seriously threatened.

Limitations of the prior art:

Aiming at the problems in busbar processing, although the prior art provides some solutions, only partial problems can be solved, and the current situations of low processing efficiency, large occupied area and difficult guarantee of processing quality can not be fundamentally changed. For example, some devices attempt to reduce the creation of indentations by optimizing the clamp design, but do not perform well, while others increase production efficiency by increasing the degree of automation, but often at the expense of machining accuracy and flexibility. These limitations make the prior art frustrating in dealing with the complex, high precision busbar processing requirements.

In order to solve the problems in the prior art, the utility model provides a highly integrated busbar punching, shearing and bending integrated machine. The equipment integrates a plurality of working procedures such as feeding, punching, shearing, bending and the like into a compact machine body, and realizes seamless connection and coordination between the working procedures through a high-precision mechanical transmission system. The design not only greatly reduces the occupied area and complexity of the equipment, but also improves the production efficiency and the processing precision.
